-alternation of generation( sporophyte and gametophyte)

-dont make seeds

Answer 2

Feature of Mosses and Fern  

Explanation:

Gametophyte and sporophyte Mosses  

• Mosses are heterosporous, which implies they make two different part of spores
• These form into male and female gametophytes,That is, the sporophyte creates just one part of spore inside a structure called the sporangium
• One gametophyte can create both male and female sex organs

Gametophyte and sporophyte Fern  

• Gametophyte is the dominant, recognizable phase of the existence cycle and the phase that does a large portion of the plant's photosynthesis
• The sporophyte is depend to the gametophyte for providing water and supplements  
• The gametophyte of ferns is a free-living organism, though the gametophyte of the gymnosperms and angiosperms is subject to the sporophyte
• A diploid sporophyte phase produces haploid spores by meiosis
